+1.  I'd be especially interested in lifting the current requirement that 
line ranges and byte ranges both increase monotonically.  Even better if 
the lines for a particular piece of code don't have to all come from the 
same file.  It'd be nice to be able to do the equivalent of '#line' 
directives for Python code that's generated by other tools, such as parser 
generators and the like.
